Isigaba 2 Ulwazi olujwayelekile

Akukho mcimbi oyobe umkhiqizi abophezeleke kuwo ngomonakalo oqondile, ongaqondile, okhethekile, wengozi noma umphumela ngenxa yanoma yikuphi ukonakala noma ukweqiwa kule manuwali. Umkhiqizi uyaligodla ilungelo lokwenza izinguquko kuleli bhukwana kanye nemikhiqizo elichazayo noma nini, ngaphandle kwesaziso noma isibopho. Ama-edishini abuyekeziwe atholakala kumakhi webindawo.

2.1 Ulwazi lokuphepha

Umkhiqizi akanasibopho sanoma yimuphi umonakalo ngenxa yokusebenzisa kabi noma ukusetshenziswa kabi kwalo mkhiqizo okuhlanganisa, ngaphandle komkhawulo, ukulimala okuqondile, kwengozi kanye nomphumela, futhi ulahla lowo monakalo ngezinga eligcwele elivunyelwe ngaphansi komthetho osebenzayo. Umsebenzisi unomthwalo wemfanelo wokubona ubungozi bohlelo lokusebenza futhi afake izindlela ezifanele zokuvikela izinqubo ngesikhathi sokungasebenzi kahle kwemishini.
Sicela ufunde lonke leli bhukwana ngaphambi kokukhipha, ukumisa noma ukusebenzisa lesi sixhobo. Naka zonke izitatimende zezingozi nezixwayiso. Ukwehluleka ukwenza lokho kungaholela ekulimaleni okubi kakhulu ku-opharetha noma ukulimala kwempahla.
Qiniseka ukuthi isivikelo esinikezwa yilesi sisetshenziswa akona. Ungasebenzisi noma ufake lesi sisetshenziswa nganoma iyiphi indlela ngaphandle kwaleyo eshiwo kuleli bhukwana.

Ukusetshenziswa kolwazi oluyingozi

INGOZI

Ibonisa isimo esingaba yingozi noma esiyingozi, uma singagwenywa, sizoholela ekufeni noma ekulimaleni okubi kakhulu.

ISEXWAYISO

Ingozi yogesi. Susa amandla esisetshenziswa ngaphambi kokuba le nqubo iqalwe.

ISEXWAYISO

Ibonisa isimo esingaba yingozi esingase sibangele ukulimala okuncane noma okulingene.

HHAYI Iqhwa

Ibonisa isimo esingaba yingozi esingase sibangele ukulimala okuncane noma okulingene.

HHAYI Iqhwa

Ibonisa isimo lapho, uma singagwenywa, singadala umonakalo entweni. Ulwazi oludinga ukugcizelelwa okukhethekile.

2.1.2 Amalebula okuqapha

Funda wonke amalebula futhi tags enamathiselwe entweni. Ukulimala komuntu siqu noma ukulimala kwethuluzi kungenzeka uma kungabonwa. Uphawu entweni esetshenziswayo lukhonjwa kubhukwana ngesitatimende sokuqapha.

	Lolu phawu, uma luphawulwe ethuluzini, lubhekisela kumanuwali weziqondiso zokusebenza kanye/noma ulwazi lokuphepha.
	Lolu phawu lubonisa ukuthi kukhona ingozi yokushaqeka kukagesi kanye/noma ukushaywa ugesi.
	Lolu phawu lubonisa ukuba khona kwemishini ezwelayo ku-Electro-static Discharge (ESD) futhi lubonisa ukuthi kufanele kuqashelwe ukuze kuvinjwe umonakalo ngempahla.
	Izinto zikagesi ezimakwe ngalolu phawu akumele zilahlwe ezinhlelweni zokulahlwa zasekhaya noma zomphakathi zaseYurophu. Buyisela izinto zokusebenza ezindala noma zokuphela kwempilo kumkhiqizi ukuze zilahlwe ngaphandle kwenkokhiso kumsebenzisi.

2.2 Umkhiqizo usuphelileview

Imojuli yokufaka engu-4-20 mA ivumela isilawuli ukuthi samukele isignali ye-analog yangaphandle (0-20 mA/4-20 mA).
Imojuli yokufaka ixhuma kwesinye sezixhumi zenzwa ye-analog ngaphakathi kwesilawuli.

2.3 Izingxenye zomkhiqizo

Qiniseka ukuthi zonke izingxenye sezitholiwe. Bheka Umfanekiso 1. Uma kukhona izinto ezingekho noma ezilimele, thintana nomkhiqizi noma omele ukuthengisa ngokushesha.

Umfanekiso 1 Izingxenye zomkhiqizo

1 4-20 mA imojuli yokufaka ye-analog	3 Ilebula ngolwazi lwezintambo
2 Isixhumi semojuli

2.4 Izimpawu ezisetshenziswa emifanekisweni

Isigaba 3 Ukufakwa

INGOZI

Izingozi eziningi. Abasebenzi abaqeqeshiwe kuphela okufanele benze imisebenzi echazwe kulesi sigaba sombhalo.

INGOZI

Ingozi yogesi. Susa amandla esisetshenziswa ngaphambi kokuba le nqubo iqalwe.

Ingozi yogesi. Ivolumu ephezulutagizintambo ze-e zesilawuli zenziwa ngemuva kwevolumu ephezulutage isithiyo endaweni ebiyelwe yesilawuli. Isithiyo kumele sihlale sikhona ngaphandle uma a
uchwepheshe wokufaka oqeqeshiwe ufaka izintambo zamandla, ama-alamu, noma ama-relay.

Ingozi yokushaqeka kukagesi. Izinto zokusebenza ezixhumeke ngaphandle kufanele zibe nokuhlola okujwayelekile kokuphepha kwezwe okusebenzayo

HHAYI Iqhwa

Qiniseka ukuthi okokusebenza kuxhunywe kuthuluzi ngokuhambisana nezidingo zendawo, zesifunda nezikazwelonke.

3.1 Ukucatshangelwa kwe-Electrostatic discharge (ESD).

HHAYI Iqhwa

Ukulimala Kwensimbi okungenzeka. Izingxenye ze-elekthronikhi ezintekenteke zingalinyazwa ugesi omile, okuholela ekusebenzeni okonakele noma ukwehluleka ekugcineni.

Bheka izinyathelo kule nqubo ukuze uvimbele ukulimala kwe-ESD ethuluzini:

Thinta indawo yensimbi esekelwe emhlabeni njenge-chassis yensimbi, ipayipi lensimbi noma ipayipi ukuze ukhiphe ugesi omile emzimbeni.

Gwema ukunyakaza ngokweqile. Izingxenye zokuthutha ezizwela u-static ezitsheni eziphikisana ne-static noma amaphakheji.
Gqoka ibhande lasesihlakaleni elixhunywe ngocingo emhlabathini.

Sebenza endaweni evikelekile engashintshi enamaphedi aphansi aqinile namabhentshi okusebenzela.

3.2 Faka imojuli

Faka imojuli kusilawuli. Bheka ezinyathelweni ezinezithombe ezilandelayo.

Amanothi:

Qiniseka ukuthi isilawuli sihambisana nemojula yokufaka ye-analog engu-4–20 mA. Xhumana nosekelo lobuchwepheshe.

Ukuze ugcine isilinganiso sendawo ebiyelwe, qiniseka ukuthi zonke izimbobo zokufinyelela zikagesi ezingasetshenzisiwe zivalwe ngesembozo sembobo yokufinyelela.
Ukuze kugcinwe isilinganiso esivalekile sethuluzi, izindlala zekhebula ezingasetshenzisiwe kufanele zixhunywe.

Xhuma imojuli kwesinye sezikhala ezimbili kwesokudla sesilawuli. Isilawuli sinezikhala ezimbili zemojuli ye-analog. Izimbobo zemojuli ye-analogi zixhumeke ngaphakathi kusiteshi sezinzwa.
Qiniseka ukuthi imojuli ye-analog kanye nenzwa yedijithali akuxhunyiwe esiteshini esifanayo. Bheka uMdwebo 2.
Qaphela: Qiniseka ukuthi kufakwa izinzwa ezimbili kuphela kusilawuli. Nakuba amachweba amabili emojula ye-analog atholakala, uma inzwa yedijithali namamojula amabili efakiwe, amadivaysi amabili kuphela kwamathathu azobonwa yisilawuli.
